Factory manual states that "the engine oil has to be changed at the intervals listed in your Maintenance Schedule" which states the following:

Minior maintenance at 20K, 60K, 100K, 140K miles etc... if the mileage for scheduled maintenance is not reached, minor maintenance must be performed after 2, 6, 10... years at the latest.

Minor maintenance for the Cayenne S and Turbo includes changing the engine oil and filter.

After searching, I understand that the OBC will give you a "maintenance required in XXX miles" warning and this warning occurs at various mileages. What triggers this warning?

Is oil quality being monitored? Surely, mileage plays a role but what else is monitored to trigger the indicator?

If the oil is changed prior to the maintenance warning, does the computer have to be "reset" or will the system just adjust to the new oil?

Just wondering since I've been putting the truck through some really tough towing miles...

is one of the few things porsche got right. notice that there is no severe service schedule. there are 2 GALLONS of one of the best, longest lived oil currently available today in that engine. very little that you can do will cause that oil to go south early, and almost nothing with a normally aspirated engine.

go to 20 and don't worry about it.

ps, i believe the indicator will trip at 20/40 etc. doing an early oil change didn't change my indicator in the slightest, although with the competency level of my dealer, they may not have known how to reset it.

Hmmn, 2 gallons, let me see, that's...no wait, don't tell me.....8 quarts?

IIRC, real Porsche engines (air cooled types, 911 and such) use, oh, I don't know, 12 quarts of oil.....about 3 gallons.

BTW, just my 2 cents from the cheap seats in the peanut gallery....

If you are, God how it hurts to say it, TOWING, I would still change the oil/filter MUCH sooner than 20K, say around 3-5K tops. I would also check/change the air filter as well.

Std practice for tow vehicles FWIW.

Thanks for the input.

For the sake of discussion, let's say I change the oil at 19K (no indicator warnings). Then within another 1K I should expect to see a maintenance indicator warning even though I have fresh oil in the motor?

So... then the choices are to purchase a stupid reset tool or to head to the local dealer for a reset, eh?

Ooops... did I say t-o-w-i-n-g? That must have been a MISTAKE!!!

The Pepper has been doing quite a fine job pulling about 6500 V-nosed pounds with a weight distributing hitch. And yes, my lights are working perfectly! !!!!!!!!!!! !

I'll probably just let the dealer mess with the oil.

Have a great Christmas!

My indicator came on with something like 2k miles and has come on right after an oil change when the dealer has forgotten to reset it.

A reset at the dealer takes 5ish minutes. It takes the dealer longer to connect/disconnect the tester than it does for them to issue the reset command.

Factory authorized service... RIGHT ON!

It looks like either time (2 yrs) or mileage (20K) are the triggers. In my case the truck was asking for service at around the 12.5K mark. Based on my mileage run rate, it would be around 2 years old when it reaches 12.5K.

I have separate thread about my situation https://rennlist.com/forums/cayenne-955-957-2003-2010/398098-cayenne-asking-for-service-at-12-5k-miles.html in case you're interested.

I know it's off-topic, but you are using a WDH? What suspension does your Cayenne have - Coils or Air?

Oils cheap ... change often. I change all my vehicles at 5K miles. I use Mobil-1 on both of my "high performance" vehicles. Our Honda CR-V (185K+ Miles) gets Dino-Oil.

of starting the oil wars, changing at 5k with mobil1 or any synthetic of any worth is a waste of money. if you are going to change at 5k, use a good SM grade dino, it will make it just fine, as your honda shows well (not to mention the fact that honda makes some of the best engines on the planet).

the two killers of oil are service shear and additive pack exhaustion. haven't seen but a few oil analysis of the V8, but it seems to be pretty easy on the oil, which combined with the large oil fill (almost twice what an american V8 would have) there is plenty of add pack left at the end of 20k. figure that the oil in a cayenne V8 has about half the usage at 20k that a ford V8 has at 10k.

i regularly run my tundra V8 and mazda 4 at 10k OCI, and have done OA's on both showing they could go alot further. the tundra V8 is easy on oil, but doesn't have the volume the cayenne does, so again, the oil does better in the cayenne.

but it doesn't hurt it much to change it sooner (it does some however, oils actually accelerate wear for about the first k of use, not enough to matter much though).

Nice reply ... learn something every day!

Old habits are sometimes hard to change - it comes from my days owning a Ford 289 in the 80s.

I'm running a full WDH with integrated sway control on the non-PASM suspension. It works like a champ.

Interesting thread, thanks. Still waiting for my maintenance indicator...

Tick... tock... tick... tock...

Does the light reset or do you need some kind of tool to do it
